It’s no mystery that Alphabet is hard at work with the Google Car. After all, it’s on its way to pave the future, and Google is poised to set the standard for self-driving cars. In its latest development, IEEE Spectrum has discovered two FCC filings regarding the search engine giant’s entry into resonant magnetic induction, also known as wireless charging.

According to the FCC documents, Alphabet’s X division, which was known before as Google[x], is aiming at disconnecting its self-driving car away from wall chargers. The company is thinking of beaming up the energy to the car itself using resonant magnetic induction.

The documents also provide info that companies that are in the business of automotive wireless charging have sent its units in Google’s headquarters in Mountain View, California. New York-based company Hevo Power and Philadelphia-based company Momentum Dynamics are given the green light to install their respective experimental chargers at Google.

Hevo Power’s prototype charger, dubbed as the Alpha, can deliver 1.5 kilowatts of energy through a circular transmitter that is “embedded like a manhole cover” in pavement. On the other hand, Momentum Dynamics wireless transmitters come with power ratings of up to 200 kilowatts. However, the FCC filings did not indicate what are the specifications of the system that Google is currently using.

At the moment, Google engineers are testing multiple chargers from the Philadelphia at the company’s headquarters as well as at the Castle Commerce Center where Google is currently testing its prototype vehicles for unmanned driving.

Wireless charging is expected to be what’s next for cars, even moreso if the technology is used by Uber and Lyft. This way, cars for such services will never run out of power during their drives. If the technology is applied and is present in different locations such as garages, parking garages, as well as other locations, then it would be enough to keep cars running even all day.
